Abstract
A one-time self-destruction type injector belongs to the technical field of a medical apparatus, which comprises a needle (1), a needle tube (2), a piston (3) and a push rod (4). The one-time self-destruction type injector is characterized in that the central portion of the outer wall of the front end of the needle tube (2) is provided with a circular groove (5), the needle (1) is sleeved on a needle connecting base which is adjacent to the circular groove (5), the front end of the push rod (4) takes a sharp shape, and the piston (3) is fixed on the outer wall of the upper portion of the tip end of the push rod (4). The one-time self-destruction type injector has the advantages of simple structure and convenient use, since the tube wall of the circular groove on the front end of the needle tube is thinner, after the transfusion of the medical liquid is finish, the piston reaches to the bottom of the needle tube, the tip of the push rod stabs the tube wall of the circular groove, the needle tube of the injector is broken, the injector can not be used again, and the purpose of one-time self destruction is achieved.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of disposable self-destruction syringe.
Background technology
At present, the disposable syringe of hospital's use mostly is to be made of syringe, push rod, piston, syringe needle.Because this syringe self can not self-destruction, after injection finishes, covers needle guard on syringe needle usually, syringe is abandoned, or syringe needle is separated the back separate recycling with syringe.If there is not the discarded management system of strict pharmaceuticals, in discarded recycling process, reclaimed by the lawless person in the society easily, after simple process, come into the market again, certainly will increase the chance of disease propagation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, easy to operate, the injection finish after syringe destroyed the disposable self-destruction syringe that syringe can't be re-used automatically.
The purpose of this utility model is achieved in that this disposable self-destruction syringe is made up of syringe needle, syringe, piston, push rod, be provided with circular groove at syringe front end outer wall middle part, be with syringe needle on the syringe needle Connection Block adjacent with circular groove, the push rod front end is tip shape, is fixing piston on the most advanced and sophisticated external wall of upper portion of push rod.
Advantage of the present utility model: simple in structure, easy to operate, because the barrel at syringe nose circle connected in star place is thinner, after injecting liquid drug is finished, piston arrives syringe bottom, the push rod tip punctures the barrel at circular groove place, and injector syringe is destroyed, syringe can't re-use, and reaches the purpose of Disposable, self-destroying.
Description of drawings
Accompanying drawing is the cutaway view of this utility model along centrage.
The specific embodiment
Make this utility model with reference to accompanying drawing: this disposable self-destruction syringe is made up of syringe needle 1, syringe 2, piston 3, push rod 4, be provided with circular groove 5 at syringe 2 front end outer walls middle part, be with syringe needle 1 on the syringe needle Connection Block adjacent with circular groove 5, push rod 4 front ends are tip shape, are fixing piston 3 on push rod 4 most advanced and sophisticated external wall of upper portion.
Claims (1)
1. disposable self-destruction syringe, form by syringe needle (1), syringe (2), piston (3), push rod (4), it is characterized in that syringe (2) front end outer wall middle part is provided with circular groove (5), be with syringe needle (1) on the syringe needle Connection Block adjacent with circular groove (5), push rod (4) front end is tip shape, is fixing piston (3) on the most advanced and sophisticated external wall of upper portion of push rod (4).
